It takes its name from an 1824 correspondence match between Edinburgh and London. Kasparov turned it into a classical weapon in his 1990s title matches.
White's plan
3.d4 opens the centre and exchanges Black's e5 pawn, gaining central space.
The knight on d4 is strong; White quickly plays Be3, Nc3 and castles.
In some lines Nxc6 damages Black's pawns and e5 gains space.
Black's plan
Pressuring the d4 knight with ...Bc5 (Classical Variation) is the most natural reply.
Attacking e4 with ...Nf6 (Schmidt Variation) gives dynamic play.
The ...d5 break is Black's main way to equalise in the centre.
Italian Game — The Italian Game is a classic 1.e4 e5 opening in which White develops the bishop to c4 and eyes the weak f7 square.
Ruy Lopez (Spanish Opening) — The Ruy Lopez (Spanish Opening) puts pressure on the knight that defends e5 with 3.Bb5 and has been the most respected 1.e4 e5 opening at the top level for centuries.
Four Knights Game — The Four Knights Game, in which both sides develop their knights to their natural squares, is symmetrical and solid—perfect for learning opening principles.
